Perfect flowy Boho daisy dress, with pockets. Fits sz M

This is only the most adorable, comfortable dress ever! pictures do not do it justice. it is a black background, with light khaki daisies pattern. It's cool, comfy, has nice, wider straps, and deep, functional pockets. It flows beautifully when you move. Dress is marked as a size Small. I am listing as a medium. it is meant to be oversized and flowing, and, as you can see, even on my size 6/8 Medium mannequin, the dress is flowing and loose. it seems to fit as it should. i think it would swallow a true sz S. measurements: pit to pit, laid flat, approx 19" top of shoulder to bottom hem, approx 46" Bin9al
